Window sash and casing



Patented Aug. 26, 193() 'firs PATENT' UFFICE OSCAR R. HANKINS, OF AURORA, ILLINOIS, AND JOACHIM R. IVI. KNUDSEN, OF MUS- KEGON, MICHIGAN; SAID HANKINS :ASSIGI-TOR 'IO .SAID KNUDSEN WINDOW SASH AND CASING Application led January 14, 1929."I Serial No. 332,448.

This invention y'relates to a metal window construction and is directedk to a particularly simple economically .constructed and eflicient window, including an outer frame or casing for the window with a window each mounted therein which may be located either in cornpletely closed position, in an outwardly inclined position or in one kof .a large number of upper inclined positions in which it will be securely held.

'I he construction of the window is fully described in the following description taken in connection with the accompanying drawing-,in which,

Fig. 1 is an elevation of the window, certain parts being broken away and yshown in section :for better disclosure of' the construction.

Fig. 2 is a tiert-ical section through the construction shown in l? ig. 1 and with chewin-v dow sash in one of its upper inclined positions, andk Y Y Fig. 3 is a fragmentary enlarged horizontal section substantially on the planeof line 3 3 of Fig. 1, loo-king downwardly as indicated by the arrows.

VLilereference characters referto like parts in the different figures of the drawing.

The outer frame orcasing of thewindow .is of sheet metal and includes two vertical ends and upper and lowersldes. Each ofthe ends is ofZ-bar form having a web 1, an inwardly turned 4flange 2 at'one edge of the web .and an outwardly turned flange 3 at theother edge of the web and at the -outer or front-side of the window. d

The upper side of the window frame is .of sheet metal and includes an outer yor front vertical flange 4 fromwhich a web section is bent vto the rear .at right angles for a distance,

'as indicated at 5, then turned downwardly to make a vertical ledge 6, and thence `again 4to the rear making a horizontal section 7 which at its rear edge is turned upwardly .at right angles toniale the vertical flange 8, the upper edge of which is positioned in substantially the same horizontal plane as the upper edge of the flange 4.

The lower side ofthe frame includes an outer vvertical flange 9, 4a 'horizontal web section 10 turned inwardly at right langles for aidistance thence downwardly making the kVertical ledge 11 and then again horizontally y'The two ends and the upper and lower sides of the frame are permanently secured at the corners of the frame preferably by welding.

At the inner side of the web 1 of each of the ends of the frame, a plate 14C of sheet metal is positioned and permanently secured, as by spot welding, at its lower end and near its rear edge being pressed inwardly to Vform the projecting portion 14a, at its forward edge haring .an iiiturned flange 15 which is inclined slightly to the Vertical and which for a portion of its intermediate length is provided with a series of spaced apart rearwardly extending.projecti-onsl therebv providing, direct-ly opposite said projections,

recesses 16a in 'the front side of the llange which recesses are spaced short distances apart as shown.

The window sash is also of sheet kmetal hav- 111gv two spaced Vertical ends and upper and lower sides.l The ends are ofZ-bar formincluding each ak'web 17, an inwardly turned rear flange 18 ,and an outwardly turned front flange 119 wh'ch is adapted to lie in front of the adjacent ange l5 previously described. Near the lower end and kat the `outer side of each web ,17 a pin 2O is permanently secured extending therefrom toward the adjacent plate 14. f

The lower .Side .of the window sash is likewise of .Z-bar forni having horizontal web 20, a downwardly extending rear flange 22 and an upwardly extending front flange 23. The upper side of the window sash is .of angle form including the horizontal leg Q4 from which` a shorter downwardly extending leg or flange 25 is bent, it together with the Aflange 22 previously described being in the same plane with .the'flanges 18 of the Z-.bar ends. These meinfbers making the .outerframe vof the window sash are welded at the corners of the Asash to V.make Aa .rigid .andperinanent construction.

The window sash carries glass panes 26 which .come against the flanges 18 and 25 and if the length of the sash is to be divided so as to carry more than onepane of glass any suitable vertical dividing partition 29 may be used for such purpose and the glass may be held in place by any suitable retaining means indicated at 27. The window sash at its upper side is equipped with the usual releasable catch 2S the structure of which is no part of the present invention.

In the assembly of the window frame or casing and the window sash the pins 2O lie bach of the flanges 15 and in the lower position of the sash in front of the projection 14n whereby the sash is held securely against undesired movement thus eliminating rattle or other` noises. The flanges 19 of the sash are in front of said flanges 15. lWhen the window is in closed position, flange 22 lies bach of the ledge 10 and the flanges 19 bear against the `flanges 15 described. he lower front edges of the webs 17 are preferably rounded so that the window may he tilted to the dotted line position shown in Fig. 2, the pins 20 bearing against the flanges 15 and the flange 22 of the window sash contacting against the flanges 2 of the Z-bar ends of the window frame. A

The window' may also be elevated, as shown in Fig. 2, and may be held in any one of a number of diiferent positions with the lower edges'of the flanges 19 seating in horizontally opposed recesses 16u while the pins 20 are disposed at the rear sides of the flanges 15 between two of the projections 16. The window sash accordingly may be raised to any number of different positions depending upon the number of recesses 16a used in the flanges 15.

This construction of window is relatively simple and economical to produce, the cost of manufacturing being low because of the simplicity of the construction and the minimum number of parts used. The ability to adjust the window to the many different positions described is a feature of considerable value. The invention is delined in the appended claims and is to he considered comprehensive of all forms of structure coming within their scope.
